We love it! Great balance of activities for kids and adults. Michelle and Dan are wonderful and take great pride in their campground. Also a beautiful area with lots to do from wineries, shopping. Playgrounds, farmers market, festivals, kayaking, sightseeing, places to eat.....

We love it at Nittany Mtn.KOA. All the years we have been staying with them, is just that..staying with them , they make you feel like you are family or an important guest. They always make sure if you need something , you get it in a timely manner, We couldn't ask for better people than Dan and michelle to take care of the campground and anyone staying there.

We're going back for our 31st YEAR in 2018! Great campground, great owners and great staff! What more can we say! No reason to look anywhere else!

We stay there every summer. In addition to many amenities, the staff is amazing. Very friendly and helpful. Year after year they are able to improve the facility and somehow find outstanding young people to work there. Five stars!

My family is a seasonal camper and we live it. Will be their for many years to come.

The staff at Nittany Mountain KOA is some of the best I've ever seen. The Owners Dan and Michele are the perfect team to run such a beautiful campground. The grounds are always well kept and the facilities are always clean. I have recommended this campground to many people and I will continue to do so in the future. Keep up the good work, we'll see you next season.. "Its a great day at the KOA"

A little off the beaten path, but makes it great for a quiet stay away from the interstate highways. Only stayed one night, but would stay again.

We always enjoy our stay at KOA Williamsport, but the Halloween weekend exceeded our expectations. This was our first time staying during the Halloween event. The activities were awesome, especially the haunted house and trail. This will be an annual stay from now on for our family and friends. No more going to the overpriced theme park campground for Halloween. Thank you!

Great Halloween weekend .... Always a fun time... :)

Oct 24, 2017

After spending a much recommended weekend at the campground and going home, emptying the camper and preparing it for winterization we just couldn't call it the end of the season without one more trip to this great campground. Halloween weekend was so much fun. Our son found friends from home there and made new friends. We look forward to staying with the KOA Nittany Mountain friends next season.

We have stayed here for many years for softball tournaments and it is the best campground. Kids and adults love it and we have traveled to quite a few campgrounds around PA. Owners are great people and the activities are so much fun. Good job KOA Nittany Mountain!!

We absolutely love going to the KOA in South Williamsport. It is extremely kid friendly with tons of great activities for the family. All of the staff put a lot of thought into it and they are always so nice and welcoming. Our favorite weekend to stay is the Halloween weekend. We come back every year. Thank you for all of the great hospitality!
